' LEON GRE N ERG, or NEW YORK, N. Y. Abvzn'rlsmcaplzvlost .Be it knownthat I, L'EoN GREENBERG, a citizen of the United States, residing at NewYork, in the county of New York and State of New York, have invented newand useful Im rovements in Advertising Devices, of which the followingis a specification. a s

This invention relates to advertisin vdevices such as are intendedsuccessive y to' display a large number of difi'erent advertlsements.

The objects of the invention are to improve and s mplify theconstruction of such devices; furthermore, to increase their efi"1uciency in operation and to decrease the expense attending theirmanufacture.

With the foregoing and. other objects in view, which will .ap ear .asthe description and claimed as a thereof. v

\ Inthe accompanying drawings, forming part of this speclfication,Figure 1 is a front elevatlon, partly in section, of an advertising- 7device constructed in accordance with my invention. Fi 2 is a fronttorear section of the same wit parts broken away to better show theconstruction. L1ke reference-numerals lndlcate corre s onding parts inthe difierent figures ofthe rawings. I

The reference-numeral 1 indicates a casing which may be'of any suitableform and'construction. The-forward end of the casing 1 i is formedwithan opening 2, in which is placed a sheet of lass. The advertisementswhich are to be isplayed show up through the opening 2. Mounted" in thecasing 1 1n any suitable manner is a pair of side plates or frames 3,each of which isformed in one corner with an elbow-section 4.

Journaled between the upper ends of the side plates is a set or pluraity of frictionrolls 5. Each of'the vfrlction-rolls 5 is provided on oneof its ends with a gear-wheel 6.

By means of the gear-wheels 6 all the rolls 5 are geared together, so asto rotate simultaneously.

The set of idle rolls 7 8 9 '10 11 12 13 1s journaled between the lowerends of the side plates 3, the rolls 7, 8, 9, and 10 being preferablyj'ournaled u on the upper on of the elbow-sections tothetwo'side'plateasoas'to I i H Specification of Letters Patent. I

provide a chamber 141-, in which is mounted a motor 15, that may be ofany suitable form and construction. The motor 15 is connected, by meansof a belt 16, with abelt-wheel 17, mounted upon the shaft of one of thefriction-rolls 5. The motor 15 serves to operate all of the frictionrolls 5 simultaneously through the gearing which connects said rollswith each other.

The advertising matter is printed or otherwise placed upon an endlessbelt '18, which extends around the friction-rolls 5, idle rolls 7 8 9 1011 12 13, and around a set of guiderolls 20, 21, 22, 23, and24,journaled between the side plates, the roll. 22 being journaled between.the elbow-sections 24, so as to hold the endless belt out of} the way ofthe motor 15. V l l It will be observed that the lower set of idle rollsis made up of seven rolls, while the upper set of friction-rolls'is madeup of fifteen. rolls. While this number may be decreased or increased,the proportion ofseven to fifteen will in most cases be maintained thatis to say, the upper set will consist of one roll more than twice thenumber of rolls in -friction roll at the top, then under the roll 12,then over the fifth friction-roll'at the top, and so on. B y

providing approximate twiceas many iction-rolls 5 as are needed foractually sup orting the endless belt the intermediate ro s act asfriction means for pressing the endless belt against the suplportingerolls around which it passes, so that all liability of-the beltslipping upon the rolls, and thus standing still whenthe rolls arerotating, is avoided.

Ha thus described the invention, what is-claime as new is 1 v Anadvertising device comprising a. casing having an opemng therein, a airof side lates' in said casing, each of sai side plates aving anelbow-section in one corner thereof, a plurality of idle rolls journaledon the elbow-section of the two lates, a plurality of similar idle rollsjournaled u on the lower ed es of the two lates, a plura ity offrictionrol s journaled etween the upper ed as of the two plates,gearing for causing sai friction-rolls to rotate simultaneously, anendless belt extending around every one of the In testimony whereof Iafiix my signature Elle rolls'afiid aroulnd (livery fother;1 one 1(1)fthe in presence of two witnesses. f
